Nothing special about the fragramatics products that I can find. I've used all kinds of consumer stuff with no perceivable difference in cleaning ability. Odoban carpet shampoo as mentioned above, Zep carpet shampoo, and the consumer carpet cleaner product called folex as a spot remover. Currently using Meguiars all purpose cleaner at a ratio of 10:1 as a spot remover, and am trying Meguiar's glass cleaner 10:1 as a shampoo, mainly for the blueberry smell. Some products if neutral pH could allow an algae buildup/slime in the tank
